Everything you see, try to sketch. It is worth mentioning that the collective observations you can give a more accurate assessment of the visible objects. Planets with astronomical observations have such a property as jitter, and the closer they are to the horizon, the stronger the vibration. Calm atmosphere is disturbed depending on the season and temperature. Be sure to mark on their sketches of the time when it was carried out astronomical observations. Try to watch from the same place under different weather conditions and at different times of day, write down all the impressions in a notebook. After analyzing their recording, you can set at what time in this place is better to conduct astronomical observations.
For astronomical observation you need a small chair, folding it is desirable that it was convenient to carry around themselves and move from place to place. You can also take with a small table on which you will be able to make astronomical notes and sketches on which you lay out the entire inventory and the book. You will also need a notebook for sketches and journal to keep track of observations, well sharpened pencil and pen. Write in the dark is not very convenient, but you can take a stand for the torch, like erecting a table lamp. Remember one thing: It is important use a flashlight with a red light – it does not blunt your night vision as opposed to white light. Locate LED flashlight with a red stream of light, or use a flashlight with red cellophane usual. You can also chill stop quickly record the results of astronomical observations, but you get used to quickly write with gloves on.
Try not to write long reports right on the spot of astronomical observations. Describe in detail what he saw can be at home, at the same place do sketches, they need to do very carefully. You can take a tape recorder and record everything that you see at home you can make a detailed report based on the records. The main rule – do not Remember to indicate in the report, when it was carried out astronomical observations. It is also necessary to note separately choose the eyepiece. In order to achieve varying degrees of increase to use different eyepieces. For example, eyepieces with focal lengths of 10 and 25 mm respectively, give 70 – and 28-fold increase. Five or more different eyepieces – common for amateur astronomers phenomenon. To calculate the magnification, use the following formula Inc .= Fok. dist. Telescope / Fok. dist. Eyepiece For example, using a telescope with a focal length of 700 mm in combination with 25-mm eyepiece gives 28x amplification. Very large gain is not achieved, because even if the image becomes large, it will be difficult to discern because of the tarnish. Therefore we should not deceive ourselves, looking at ads with loud statements about the ability of the device – it's just a publicity stunt. Regardless of the object of observation, Always start with an eyepiece, which gives the minimum power (longest focal length) to target an object. This will allow you to get more visibility. Only then should gradually increase the picture.
